BACKGROUND OF THE INVENTION

1. Field of the Invention

Our invention relates to novel lighting devices which provide light forillumination as well as ambient light.

2. Description of Related Art

Electric lamps, and the light bulbs used therein, which provideillumination are well known and are widely used. These lamps and bulbsfall into two general categories, namely, incandescent and fluorescent.More recent developments in lighting have led to advancement in lightemitting diodes (LEDs). An LED is a semiconductor device that emitsvisible light when an electrical current passes through it. The lightfrom an LED is basically monochromatic and the color of the light isdetermined by the particular material used in the semiconductor(although current applied to the LED can be used to vary the perceivedcolor). LEDs have the advantage of low power requirements, highefficiency and long life. The outputs of several different color LEDscan be mixed so as to produce additional colors, including white light,and different brightness. LEDs can also be used to provide backgroundlighting to achieve desired ambient effects. However, they have limitedbrightness and therefore they are generally not suitable forillumination purposes. Instead, LEDs have been generally used for suchapplications as indicator lights, panel backlighting and fiber opticdata transmission.

U.S. Pat. No. 6,149,283 discloses an LED lamp/bulb having a multicoloradjustor. This device comprises a base in which several LEDs capable ofproducing different colored light are mounted. Adjustable switches areprovided for the different color LEDs so that the colors can be mixed inany desired ratio to produce desired lighting effects such as varyingcolors, including white light, and varying brightness. This patentacknowledges that the lumen output of LEDs is not as high as anincandescent source of the identical wattage.

U.S. Pat. No. 5,924,784 discloses providing ambient light (simulating acandle flame) from both a free-standing lamp and an Edison-style lightbulb (i.e., a screw-in bulb that mates with a conventional light bulbsocket) using LEDs. The flame simulation is provided through both colorcombinations emitted and flicker effects. The patent states that it isdirected to bulbs and lamps used for achieving soothing effects inmemorials and the like.

U.S. Pat. Nos. 6,016,038, 6,150,774, 6,166,496, 6,211,626, 6,292,901 and6,340,868 disclose various techniques and electrical circuits forcontrolling the light output of several LEDs according to predeterminedprograms.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in FIG. 1, a lamp 10 according to one embodiment of ourinvention includes a base 12 having a flat bottom 14, which may rest ona horizontal surface, such as a table top or a desk, and a translucentshade 16, which extends up from the base and which permits lightgenerated therein to be emitted out from the lamp. The base 12 includesa bulb support 18 near its upper end. The bulb support 18 serves as amounting for a plurality of light emitting diodes (LEDs) 20 as well as asocket 22 for an illumination bulb 24, which may be, for example, aconventional, screw-in incandescent bulb. As can be seen, the LEDs 20and the illumination bulb 24 are positioned so that light generated fromthese devices can be emitted through the shade 16.

The bulb support 18, as shown in FIG. 2, has an outer portion 18 a inthe form of a ring; and the LEDs 20 are distributed around this outerportion. The bulb support 18 also includes a center portion 18 b whichsupports the illumination bulb socket 22.

A first electrical circuit 26 is provided in the base 12 and isconnected to supply electrical power to each of the LEDs 20. A secondelectrical circuit 28, also provided in the base 12, is connected tosupply electrical power to the illumination bulb socket 22. A switchcircuit 30 is also provided in the base 12 and is connected to supplyelectrical power to the first and second electrical circuits 26 and 28.The switch circuit 30 is connected to a power line 32, which may receiveelectrical power from a battery (not shown) contained within the lampbase 12, or from an outside source such as a household electricaloutput.

The switch circuit 30 includes a program control unit 34, which isconfigured to switch electrical power to the first and second electricalcircuits 26 and 28 as desired, i.e., either to both simultaneously or toeach alternately, depending on the type of light to be produced by thelamp 10. The program control unit includes control switch actuators 34,which are located on the base 12 for manual adjustment of the outputintensity or brightness of the LEDs 20 and of the illumination bulb 24.The program control unit 34 may also incorporate an internal program andassociated circuits which provide adjustment of the LEDs 20 and theillumination bulb 24 in a predetermined manner. This can provideselectable light shows among which a user may choose. In addition,sensors (not shown) may be provided to sense other conditions in thearea of the lamp 10, e.g., temperature, scent, sound, motion, etc., andto adjust the program in the program control unit 34 so as to coordinatethe light outputs from the lamp 10 with such sensed conditions.

As shown in FIG. 3, an Edison-style light bulb 40 according to anotherembodiment of the invention includes a threaded, Edison-style base 42for use with conventional light bulb sockets. (Of course, the bulb maybe configured to mount in other conventional sockets for mounting lightbulbs, such as fluorescent and halogen.) A translucent housing 46extends up from base 42. The translucent housing 46 allows lightgenerated therein to be emitted from the bulb.

A lighting support 48 is positioned within housing 46, and serves as amounting for a plurality of LEDs 50 and an illumination source mountingsocket 52. Socket 52 mounts, and provides power to, an incandescentillumination source 54. Light generated by the LEDs 50 and illuminationsource 54 is emitted through housing 46. Housing 46 may be releasablysecured to base 42, to allow for replacement of illumination source 54.

The light source support 48, as shown in FIG. 4, has an outer portion 48a in the form of a ring. The LEDs 50 are distributed around this outerportion. The light source support 48 also includes a center portion 48 bwhich supports socket 52, or the illumination source 54, when theillumination source 54 is fixedly mounted on support 48 without asocket. A socket is preferably used in order to allow for replacement ofburned out illumination sources, since the LEDs 56 are expected tooutlast any conventional illumination source.

A first electrical circuit 56 is connected to supply electrical power toeach of the LEDs 50. A second electrical circuit 58 is connected tosupply electrical power to illumination source 54. Also provided is aswitch circuit 60, which is connected to supply electrical power to thefirst and second electrical circuits 56 and 58. The switch circuit 60 isconnected to power supply line 62, which receives electrical power froman Edison-style light bulb socket when mounted thereon. The switchcircuit 60 includes a program control unit 64, which is configured toswitch electrical power to the first and second electrical circuits 56and 58 as desired, depending on the type of light to be produced. Theprogram control unit 64 includes control switch actuators 64 a, whichare located on the outside of housing 46. The control switch actuators64 a provide for switching between different modes of lightpresentation, i.e., activating either one of first and second electricalcircuits 56 and 58, or activating both simultaneously. The programcontrol unit 64 also includes switch actuators 64 b, also located on theoutside housing 46, for manual adjustment of, for example, the outputintensity or brightness of the LEDs 50 and illumination source 54,pre-programmed light shows using the LEDs 50, the color of the lightprovided by the LEDs 50, etc. The control switch actuators 64 b mayoperate by controlling internal programs and associated circuits ofprogram control unit 64. In addition, any one of a number of controlmechanisms may be used in keeping with the present invention includingmicroprocessors, mechanical activity devices, software driven control,and the like. Also, we have referred to the depicted LEDs 50 as separatelight emitting diodes; however, the depicted LEDs 50 may also beindividual groups of light emitting diodes. For instance, a single LEDgroup 50 may include three individual light emitting diodes specific tocolors red, green, and blue, respectively. With such a configuration,the program control unit 64 may individually set the relative intensityof each of the light emitting diodes of each group so as to control thecolor emitted from those groups, i.e., the color emitted from a depictedLED group 50 may be varied based on the combination of colors from theindividual light emitting diodes of the group. A user may perceive thecombined color by way of positioning the individual diodes of an LEDgroup 50 so closely together as to produce an overall color effect, oralternatively, a translucent shade (e.g., a diffuser) 52 may be providedto cover each LED 50, thus providing for a single perceived color to beemitted from each shade 52 as if it were a single pixel.

The program control unit 64 further includes a sensor input 66 forreceiving signals from a sensor 66 a. Sensor 66 a may be provided on thelight bulb 40 or at a remote location. When positioned at a remotelocation, signals from sensor 66 a may be transmitted to the sensorinput 66 by way of a direct connection or a wireless connection (i.e.,radio signal, infrared signal, etc.).

Sensor 66 a may sense such stimuli as temperature, sound, motion, etc.The program control unit 64 may adjust a program for operation of LEDs50 and illumination source 54 based on the sensed conditions.

In addition, control signals may also be provided by direct connectionor a wireless connection by a user, rather than a sensor. For instance,as regards direct connection, a user may simply vary the application ofthe power source by toggling a power switch which controls the powersupply to the device with which bulb 40 is mated. In this case, thesensor input 66 may sense the power supply and change the control of thedevice based on the timing of the activation and deactivation of thepower supply. Alternatively, a remote control may be provided so that auser may send control signals (e.g., radio signals, infrared signals,etc.) to the sensor input 66. These control options may be provided inaddition to or in lieu of switches 64 a and 64 b.

FIG. 5 shows an Edison-style light bulb 70 according to yet anotherembodiment of our invention. In this embodiment, a fluorescentillumination source 55 is mounted on a socket 53. Of course, theillumination may be provided in a conventional light bulb socket, whichallows for replacement of the bulb, or alternatively may be a lightingdevice permanently affixed to a device according to our invention. Theremainder of the features of light bulb 70 are similar to thelike-numbered features discussed above with respect to light bulb 40,shown in FIG. 3.

FIGS. 6A and 6B show another embodiment of our invention embodied inbulb 100. Bulb 100 is similar to previous embodiments in that itincludes a base 140 having a screw-in connector 150 adapted to mate witha conventional incandescent light bulb socket in a lamp or the like. Ofcourse, connector 150 may be of any one of a number of configurationsthat mate with other conventional light sockets (e.g., fluorescent,halogen, etc.).

Bulb 100 also includes a translucent housing 130. Housing 130 enclosesbulbs 110. While other light emitting devices may be provided to providethe bright, white light associated with conventional light bulbs, it ispreferred that compact fluorescent bulbs be used. (Of course, bulbs 10may be replaceable light bulbs, or more permanently affixed lightemitting devices.) In this embodiment, we will discuss a plurality ofcompact fluorescent bulbs which are provided to increase the power ofthe bulb 100 and the overall surface area within housing 130 emittingwhite light (or the like).

As is shown in FIG. 6A, compact fluorescent bulbs 110 are each formed inan upside down, substantially U-shaped configuration. (Of course, otherarrangements are possible while keeping with the scope of ourinvention). In particular, a compact fluorescent bulb 110 may have afirst electrode at one end from which it extends up in a direction awayfrom base 140, until it bends back on itself near the top of housing130, so as to extend back toward base 140 to a second electrode at theother end. FIGS. 6A and 6B show two such bulbs 110.

Alternatively, compact fluorescent bulbs 110 can be formed of a singlebulb that has a plurality of separate lengths, each of which extends upfrom the base 140 and then bends back on itself to extend back to base140, with the lengths being interconnected so as to have only twoelectrodes, each at opposite ends of the total length. Morespecifically, while FIGS. 6A and 6B appear to show two separate U-shapedbulbs, the term plurality of compact fluorescent bulbs used within thisspecification can refer to a single compact fluorescent bulb that isbent multiple times to have distinct lengths, as shown in FIGS. 6A and6B.

In a most preferred embodiment, the total length of the multiple compactfluorescent bulbs 110 is in the range of about 2 to about 21 inches,whether the compact fluorescent bulbs are actually distinct bulbs, or asingle bulb having a plurality of distinct lengths. Preferably, thiscould include about 1 inch lengths, with one bend, to about 3.5 inchlengths, with 1 to 3 bends. This provides a high surface area of lightemission to provide ample light to illuminate a room or the like. Also,it should be noted that any number of shapes and configurations may beused to form compact fluorescent bulbs 110 (or other bulbs), other thanthe U-shaped configuration shown in the figures. For instance, spiral orhelical shapes may be used.

Bulb 100 also includes a plurality of LEDs 120. Similar to embodimentsdiscussed above, LEDs 120 are arranged on an LED board 122 so as toencircle the compact fluorescent bulbs 110. In addition, LEDs 120include a number of different color LEDs. More specifically, as shown inthis embodiment, the LEDs of different colors are arranged such thatadjacent individual LEDs 120 a and LEDs 120 b are LEDs of differentcolors. With such a configuration, the different colored LEDs may beevenly spaced around the inside of housing 130 to provide a suitablelight display when perceived from any side of bulb 100. As discussedabove with respect to other embodiments, the LEDs may also be configureddifferently such that a grouping of different colored LEDs may bepositioned close to each other (and optionally, covered by a lightdiffuser so that the group acts as a single pixel) to give increasedcontrol over the perception by a user of the colors to be emitted fromhousing 130. In such embodiments, LEDs 120 may be controlled to providea more fluid, continuous change between different emitted colors (e.g.,color wash). In the embodiment shown in FIGS. 6A and 6B, the separationof differently colored LEDs 120 a and 120 b provides a more distinct anddelineated change of. colors, as perceived by user, in comparison withan embodiment in which a group of differently colored LEDs 120 arepositioned close to each other so as to be perceived by user as a singlepixel. Alternatively, the arrangement may include close groupings ofLEDs, with individual LEDs or the grouping still being separatelydiscernable.

LEDs 120, compact fluorescent bulbs 110 and LED board 122 are mounted onbase 140, directly or indirectly. Base 140 includes a control circuitboard 160 which includes LED power supply 164 and compact fluorescentbulb power supply 162. By providing power (and control) for thesefeatures on one board, a more compact bulb 100 is achieved. Board 160may include conventional switches and potentiometers for controlling thefunctions of the LEDs 120 and fluorescent bulbs 110, as would beunderstood by one of ordinary skill in the art. Alternatively, separateboards may be provided for LEDs 120 and compact fluorescent bulbs 110.Electrical power is supplied to board 160 through its electricalconnection (not shown) to connector 150, which receives power when matedwith a conventional light socket.

Control board 160 may also include a processor 166 that may use variouscombinations of software and hardware to control the various lightingfunctions. With respect to LEDs 120, the control may involve control ofthe color to be emitted by LEDs 120, individually or as a group, whenperceived by a user from outside of housing 130 (this may involve theuse of a diffuser or the like). In addition, the control mechanisms maycontrol the brightness of the LEDs 120. Further, the control may involvethe running of predetermined lighting presentations (e.g., light shows)that vary the light color, brightness, activation, etc., over the courseof the presentation to provide an entertaining lighting show. Thecontrol mechanisms may also control the compact fluorescent bulbs 110,including their brightness or activation. In preferred embodiments, thecompact fluorescent bulbs 110 are activated on their own, without LEDs120, to provide normal white light for illuminating a room or otherarea. The LEDs may be used separately as night lights or to provideambience using color features or color shows that are pleasing to auser.

The light shows may be stored in a memory 168, which may also beincluded on the control board 160 (or integrated with processor 166).The memory 168 may include software programs for controlling the circuitboard 160 and/or processor 166 to operate the predeterminedpresentations.

A user interface 170 is provided on base 140 so as to provide a userwith control of the control board 160 and/or processor 166. The userinterface may allow the user to select the colors, brightness,activation, etc. of the LEDs 120 and compact fluorescent bulbs 110. Inthe depicted embodiment, the user interface 170 is a button which a usercan toggle to switch between different settings. In other embodiments,user interface 170 may be more elaborate (and be provided at base 140,or remote locations) so as to allow a user more sophisticated control ofthe operation of the bulb 100. This could include the ability to designprograms including color changes, changes in brightness of variouscomponents, timed activations and/or deactivations, etc., andcombinations thereof.

FIGS. 7-9 show a modification of the bulb shown in FIGS. 6A and 6B. Inparticular, there are provided three compact fluorescent bulbs 110(which may include three distinct fluorescent bulbs or three distinctlengths of light emission of a single fluorescent bulb). Again, theseparate compact fluorescent bulbs 110 are provided so as to extend fromthe base 140 vertically up through the housing 130 to a position nearthe top thereof. In this embodiment, however, LEDs 120 are not arrangedcircularly around the compact fluorescent bulbs 110 near the base 140,but are arranged in vertical groupings, each grouping extending betweenseparate compact fluorescent bulbs 110. As shown in FIG. 9, eachgrouping of LEDs 120 extending between adjacent compact fluorescentbulbs 110 may be secured to a separate LED board 122. This provides aslightly different lighting effect that may distribute colored lightmore effectively.

With the above-described various embodiments, our invention provides abulb similar in size, shape and compatibility to conventional lightbulbs, but with enhanced features and control, including colors, colorchanging and light shows. However, because our invention still mateswith conventional light sockets, and is generally shaped similarly tothat of a conventional incandescent bulb (at least in one embodiment),it may be used in existing light fixtures and accommodate conventionallight shades. Specifically, housing 130 is preferably shaped/sized so asto be able to receive the connection means provided on conventionallight shades to secure the same to typical light bulbs. In particular,with respect to FIG. 6A, the diameter of housing 130 at position 132 (awider top portion of housing 130) is preferably in the range of about1.75 to about 3.25 inches, and the diameter of housing 130 at position134 is preferably about 1 to about 3 inches. Most preferably the of thebulb substantially complies with conventional bulb sizes A-19 (withposition 132 measuring about 2.375 inches) and A-21 (with position 132measuring about 2.625 inches).

In addition, bulb 100 preferably emits white light from compactfluorescent bulbs, or other light emission devices in a range of about160 to about 4200 lumens; and more preferably in the range of about 240to about 2625 lumens; and most preferably in the range of about 320 toabout 2100 lumens. Also, a bulb according to our invention preferablydraws power in the range of about 5 to about 200 watts; and morepreferably in a range of about 15 to about 125 watts; and mostpreferably in a range of about 25 to about 100 watts. Consequently, ourinvention is designed for use in many settings where conventional bulbswould typically be used.

It should also be recognized, however, that other suitable illuminationsources, such as a halogen bulb or high intensity discharge bulb, may beused to provide illumination light, as would be readily understood byone of ordinary skill in the art.
